This following might have been mentioned in this this thread. The battery can fail in multiple ways shorted cell, bad cell, case cracked etc. Leaving the jumpstarter connected for 10 minutes might work but it might also discharge it to the point where you are stranded. Not knowing what the problem is, I would disconnect the negative battery cable and attach the jumpstarter. After the contactors close and the DC-to-DC converter is enabled, the car does not require a 12V source. Remove the jumpstarter after the car is awake/operational. Turn on sentry mode so the car does not go back to sleep until you get home/replace the battery. I responded to another thread in this forum a while back with the suggestion to remove the negative cable and it worked for the owner. If anyone sees a flaw using this procedure or something that might cause further damage please respond.
A23 battery in pocket, jumpstarter and 10MM wrench in frunk. Note: most jumpstarters require a minimum voltage they use to detect reverse polarity; therefore, you need to know how to manually enable the voltage output on the unit you own/purchase.
A23 battery in pocket, jumpstarter and 10MM wrench in frunk is exactly what I plan to do after reading through this thread, thanks all for the input. I haven't had any issues with my battery, but would like to be prepared if this does happen.
